[0004] However, in the above method, since the analysis server can only detect the time delay of the data message between multiple switches, and the time delay between the multiple switches can only reflect whether there is an abnormality in the communication system, it cannot Reflects the specific location of the abnormality in the communication system, so this method cannot accurately find out the specific location of the abnormality in the communication system

Embodiment Construction
[0052] The terms "first" and "second" in the specification and claims of the present invention are used to distinguish different objects, rather than to describe a specific order of objects. For example, the first data packet and the second data packet are used to distinguish different data packets, rather than describing a specific sequence of data packets.
[0053] In the embodiments of the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.
[0054] In the description of the present invention, unless otherwise specified, the meaning of "plurality" refers to two or ...

The embodiment of the invention provides a method, a device and a system for detecting time delay, and relates to the technical field of communication, and an abnormal specific position in a communication system can be accurately found out. A switch receives a first data message sent by a last-hop device. The switch generates a second data message by adding the first time and the second time intothe first data message. The first time is the time of the switch receiving the first data message sent by the last-hop device, and the second time is the time of forwarding the first data message to the next-hop device by the switch. The switch sends the second data message to an analysis server, and the analysis server and the next-hop device are different equipment. The analysis server receivesthe second data message, and the analysis server determines the time delay of the first data message in the switch according to the first time and the second time.
Description
technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device and system for detecting time delay. Background technique [0002] In a communication system, there may be a certain transmission delay (hereinafter referred to as delay) when data packets are forwarded between two hosts through a switch. Since the time delay can reflect the abnormality of the communication system, it can be determined whether there is an abnormality in the communication system by detecting the time delay of data packets between switches. [0003] Suppose two hosts in a communication system (such as figure 1 Host 1 and host 2 in the communication system shown) through multiple switches (such as figure 1 The switch S1, the switch S2, the switch S3 and the switch S4) in the communication system shown forward the data message in sequence. When the detection data packet is in such as figure 1 The time delay...
